2 LAY SUMMARY Eprosartan 300mg, 400mg and 600mg film-coated tablets. (eprosartan mesilate) This is a summary of the Public Assessment Report (PAR) for Eprosartan 300mg film-coated tablets (PL 37222/0027, previously PL 31746/0006), Eprosartan 400mg film-coated tablets (PL 37222/0028, previously PL 31746/0007) and Eprosartan 600mg film-coated tablets (PL 37222/0029, previously PL 31746/0008). It explains how Eprosartan 300mg, 400mg and 600mg film-coated tablets were assessed and their authorisation recommended, as well as the conditions of use. It is not intended to provide practical advice on how to use Eprosartan 300mg, 400mg and 600mg filmcoated tablets. For practical information about using Eprosartan 300mg, 400mg and 600mg filmcoated tablets, patients should read the package leaflet or contact their doctor or pharmacist. What are Eprosartan 300mg, 400mg and 600mg film-coated tablets and what are they used for? Eprosartan 300mg, 400mg and 600mg film-coated tablets are generic medicines. This means that Eprosartan 300mg, 400mg and 600mg film-coated tablets are similar to a reference medicine already authorised in the European Union (EU) called Teveten 300 mg, 400 mg and 600 mg film-coated tablets (SmithKline and Beecham PLC trading as SmithKline Beecham Pharmaceuticals). Eprosartan 300mg, 400mg and 600mg film-coated tablets contain the active ingredient, eprosartan mesilate which belongs to a group of medicines called angiotensin II receptor antagonists. This medicine is used to treat high blood pressure, also called hypertension. The main cause of high blood pressure is narrowing of the blood vessels. This increases the amount of work the heart must do to pump blood around the body. The patient may not feel unwell, but if high blood pressure is not treated, it can lead to heart disease and stroke. How do Eprosartan 300mg, 400mg and 600mg film-coated tablets work? Angiotensin II is a chemical found in the body which makes the blood vessels contract. This makes it more difficult for blood to pass through them. This causes the blood pressure to rise. This medicine works by preventing the chemical, angiotensin II, from causing the blood vessels to contract. This has the effect of lowering the blood pressure. The patient may be given eprosartan mesilate on its own or with another medicine used to treat high blood pressure. Using both medicines together will lower the blood pressure more than one on its own. 2

3 How are Eprosartan 300mg, 400mg and 600mg film-coated tablets used? Eprosartan 300mg, 400mg and 600mg film-coated tablets can be obtained only with a prescription. This medicine should be taken exactly as advised by the prescribing doctor. The recommended starting dose for adults is 600mg once a day which may be increased to 800mg once a day (two 400mg tablets) by the patient s doctor. Eprosartan 300mg, 400mg and 600mg film-coated tablets are taken by mouth at exactly the same time each day. The tablets may be taken with or without food. The patient s doctor will tell the patient how many tablets to take and for how long. It is important that the patient takes the tablets for as long as their doctor has told them to. The patient should only remove a tablet from the blister strip when it is time to take their medicine. For further information on how Eprosartan 300mg, 400mg and 600mg film-coated tablets are used, refer to the package leaflet and Summary of Product Characteristics available on the Medicines and Healthcare products Regulatory Agency (MHRA) website. What benefits of Eprosartan 300mg, 400mg and 600mg film-coated tablets have been shown in studies? As Eprosartan 300mg, 400mg and 600mg film-coated tablets are generic medicines; studies in patients have been limited to tests to determine that the tablets are similar to the reference medicine, Teveten 300 mg, 400 mg and 600 mg film-coated tablets (SmithKline and Beecham PLC). Two medicines are bioequivalent when they produce the same levels of the active substance in the body. What are the possible side effects of Eprosartan 300mg, 400mg and 600mg filmcoated tablets? Because Eprosartan 300mg, 400mg and 600mg film-coated tablets are generic medicines and are bioequivalent to the reference medicine, the benefits and possible effects are taken as being the same as those for the reference medicine. For the full list of restrictions, see the package leaflet available on the MHRA website. Why are Eprosartan 300mg, 400mg and 600mg film-coated tablets approved? It was concluded that, in accordance with EU requirements, Eprosartan 300mg, 400mg and 600mg film-coated tablets have been shown to have comparable quality and to be bioequivalent to Teveten 300 mg, 400 mg and 600 mg film-coated tablets (SmithKline and Beecham PLC). Therefore, the MHRA decided that, as for Teveten 300 mg, 400 mg and 600 mg film-coated tablets (SmithKline and Beecham PLC) the benefits are greater than the risks and recommended that they can be approved for use. 3

11 CLINICAL ASSESSMENT CLINICAL PHARMACOLOGY BIOEQUIVALENCE In support of these applications, the Marketing Authorisation holder has submitted a bioequivalence study: A randomised, open label, balanced, single center, two-treatment, two-period, two-sequence, single dose, crossover bioequivalence study of Eprosartan Mesylate 600 mg tablets (Test) and TEVETEN 600 mg tablets (Reference) in healthy adult, male, human subjects under fed conditions. The pre-dose sample was collected within 1 hour prior to drug administration. The post-dose blood samples were collected at 0.33, 0.66, 1.00, 1.33, 1.66, 2.00, 2.33, 2.66, 3.00, 3.33, 3.66, 4.00, 4.33, 4.66, 5.00, 5.33, 5.66, 6.00, 7.00, 8.00, 10.00, 12.00, 16.00, and hours after drug administration in each study period. The blood sampling up to hours was done in-house. There was a washout period of 7 days between the dosings. Ratio and 90% Confidence Intervals of Test versus Reference for Eprosartan (Linear Log Trapezoidal) The results showed that the 90% confidence intervals for AUC and C max fell within the acceptable range ( %). Bioequivalence has been shown for the test formulation (Eprosartan Mesylate 600 mg tablets) and the reference formulation (TEVETEN 600 mg tablets). A justification with regard to the linearity of the drug substance pharmacokinetics over the dose range from 300 mg to 600 mg has been accepted. The 300 mg, 400 mg and 600 mg tablet strengths meet the biowaiver criteria as specified in the Guidance on the Investigation of Bioequivalence (CPMP/EWP/QWP/1401/98 Rev. 1/Corr**) hence the results and conclusions from the bioequivalence study with the 600 mg strength can be extrapolated to the 300 mg and 400 mg strengths. EFFICACY No new efficacy data have been submitted and none are required for these applications. SAFETY No new safety data have been submitted and none are required for these applications. EXPERT REPORT The clinical overview is written by an appropriately qualified physician and is a suitable summary of the clinical aspects of the dossier. 11

12 SUMMARY OF PRODUCT CHARACTERISTICS These are satisfactory. PATIENT INFORMATION LEAFLET This is satisfactory. LABELLING These are satisfactory MAA FORM These are satisfactory. CONCLUSIONS There are no objections to the approval of these products from a clinical point of view. 12

13 OVERALL CONCLUSION AND RISK BENEFIT ASSESSMENT QUALITY The important quality characteristics of Eprosartan 300 mg, 400 mg and 600 mg Filmcoated Tablets are well defined and controlled. The specifications and batch analytical results indicate consistency from batch to batch. There are no outstanding quality issues that would have a negative impact on the benefit/risk balance. NON-CLINICAL No new non-clinical data were submitted and none are required for applications of these type. EFFICACY With the exception of the bioequivalence study, no new data have been submitted and none are required for applications of these type. Bioequivalence has been demonstrated between the applicant s Eprosartan Mesylate 600 mg Film-coated tablets and the reference product, TEVETEN 600 mg tablets. As the 300 mg, 400 mg and 600 mg Film-coated tablet strengths meet the biowaiver criteria as specified in the Guidance on the Investigation of Bioequivalence (CPMP/EWP/QWP/1401/98 Rev. 1/Corr**), the results and conclusions from the bioequivalence study with the 600 mg strength can be extrapolated to the 300 mg and 400 mg strengths. SAFETY No new or unexpected safety concerns arise from these applications. PRODUCT LITERATURE The SmPCs, PIL and labels are acceptable. The SmPCs are consistent with those for the originator products. The PIL is consistent with the SmPCs and in line with current guidelines. The labellings are in line with current guidelines. RISK BENEFIT ASSESSMENT The quality of the products is acceptable and no new non-clinical or clinical concerns have been identified. Extensive clinical experience with eprosartan mesilate is considered to have demonstrated the therapeutic value of the compound. The risk benefit assessment is, therefore, considered to be positive. 13
